Consider the Dtrace providers made available in Oracle Linux.
Which three providers are valid Oracle Linux Dtrace providers? (Choose three.)
A B D
Examine the contents of /etc/mail/access:
This system is to be used as an MTA or mail gateway for the local LAN network address 192.168.1.0/24.
Which two actions allow this mail host to route email for the network?
Which two statements are true about debugging OCFS2?
o2image copies the OCFS2 file system meta-data from the device to the specified image-file. This image file contains the file
system skeleton that includes the inodes, directory names and file names. It does not include any file data.
This image file can be useful to debug certain problems that are not reproducible otherwise. Like on-disk corruptions. It could
also be used to analyse the file system layout in an aging file system with an eye towards improving performance.
As the image-file contains a copy of all the meta-data blocks, it can be a large file. By default, it is created in a packed
format, in which all meta-data blocks are written back-to-back. With the -r option, the user could choose to have the file in the
raw (or sparse) format, in which the blocks are written to the same offset as they are on the device. debugfs.ocfs2
understands both formats.
Which two can be selected when using rescue mode in Oracle Linux? (Choose two.)
Which two parameters are valid networking modes for a Linux container (LXC)?

Which two actions are Linux containers best suited to perform? (Choose two.)
